Abstract:
Objective:To analyze the factors influencing pH value in umbilical arterial blood gas (UABG) analysis in preterm infants.Methods:A retrospective study was conducted on live singleton preterm infants ( n=573) who received UABG analysis in Peking University Third Hospital from January 2017 to February 2019. Analysis of variance, independent sample t-test, Spearman's or Pearson's correlation analysis, or linear regression analysis was used to analyze the influencing factors. Results:There was no significant difference in UABG pH value between preterm infants of different gestational ages (F=1.74, P=0.077). Spearman's correlation analysis found no correlation between gestational age and UABG pH value in premature infants ( r=0.003, P=0.940), and neither did Pearson's correlation between birth weight and pH value ( r=0.025, P=0.548). UABG pH value in preterm infants was linearly correlated with vaginal delivery ( t=－5.72, P<0.001), gestational hypertension ( t=－3.99, P<0.001) and placental abruption ( t=－4.52, P<0.001). Conclusions:Preterm infants at different gestational ages show a similar pH value in UABG. For those born to mothers with gestational hypertension or placental abruption, when vaginal delivery is pending, close monitoring and full preparation for resuscitation are necessary.
